Objective International migration to the U.S. suburbs has upended many theories of urban inequality and immigrant incorporation, including ethnic economy theory. This article is the most comprehensive study conducted to date on the reasons behind ethnic economy suburbanization and its effect on earnings. Methods The article uses regression techniques to analyze Census microdata from 1990 to 2010. A series of analyses that aggregate and disaggregate trends across nine ethnic groups identify the extent and influence of ethnic economies in suburban areas. Results Ethnic economy suburbanization is strongly associated with ethnic residential suburbanization, and earnings are no different in the suburban and urban portions of the ethnic economy. Conclusion Although existing research highlights the uniqueness of suburban ethnic economies, suburban ethnic economies are delivering outcomes similar to those found in urban areas. This supports the body of literature arguing that differences between immigrant incorporation patterns in cities and suburbs are diminishing.
